A line-and-space structure having a line portion and a space portion is formed by applying a sol-gel coating on a substrate and transferring a structure of a mold to the coating, and an embedded metal portion is formed by filling the space portion with a molten metal. As the metal to be molten, a metal material having a melting point of not higher than 650° C. and showing, after the solidification, an average extinction coefficient of higher than 5.0 or an average extinction coefficient of higher than 4.5 and an average refractive index of less than 1, at a wavelength range of 400 to 700 nm, is selected to improve optical characteristics. |
